PROBLEM TO BE SOLVED: To improve thermal resistance and color stability of a polyester composition without imparting an adverse effect to hydrolysis stability, and to increase impact resistance of a polyester resin which is stable to hydrolysis, and to sustain impact resistance and color in heat aging. SOLUTION: A thermoplastic resin composition for molding comprises an alkylene aryl polyester, a core-shell type impact modifier for increasing heat resistance having a shell derived from an alkylacrylate and a rubbery acrylate core derived from an acrylate having 4 to 12 carbon atoms, an effective amount of a bifunctional epoxy compound for increasing hydrolysis resistance of resins, and a combination of color enhancing stabilizers comprising a thioester stabilizer, a phosphite or phosphonite stabilizer and a hindered phenol stabilizer.
